Redesign Provides Better Balance to Mower


Cast Component


Cast Component:: Bumper. Material: Gray iron.


Process: Vertically parted green sand casting. Application: Commercial lawn care.


Casting Supplier: Waupaca Foundry Inc. Plant 1, Waupaca, Wisconsin


Dimensions: 7 x 13 in. Customer: John Deere Turf Care.


• T is two-piece bumper replaced a one-piece design that wrapped around the mower, displacing the center of gravity. T e new version weighed less, reduced machining needed and allowed for more effi cient packing and shipping.





Mounting holes that were drilled and tapped at an off set machining facility are now cast in the mold without the use of cores, eliminating any secondary machining operations.


• T e casting facility engineered the pattern so three castings per mold could be produced for faster production.
